A hydrogen bond is formed when a positively polarized hydrogen atom in one molecule is attracted to a highly electronegative atom in another molecule. In the example of water molecules, the negatively charged oxygen atom in one water molecule attracts the positively charged hydrogen atom in another water molecule. Oxygen atoms tend to steal electrons away from the hydrogen atoms within molecules. When this occurs within a water molecule, the electron loss creates a hydrogen atom with a partial positive charge, which is then attracted to a negatively charged oxygen atom in another water molecule.
The hydrogen bonds that form between water molecules cause them to stick together. This gives water a high boiling point temperature because a greater degree of heat energy is required to break the intermolecular hydrogen bonds. Many organic substances that are required to sustain life, such as nucleic acids and proteins, contain hydrogen bonds. Although these bonds are weaker than the internal ionic or covalent bonds existing between the atoms within molecules, the accumulated strength of hydrogen bonds within living organisms is highly significant and plays an important role in maintaining stability.
B. False, muscle mass may weigh the same as fat but fat is much bigger and fatter than muscle weight
D.the data for the average heights of the plant in trial 1 and 3 contains errors
Answer:
It decreases cost of production on the crop as well as increase production.
Explanation:
It is a very efficient method to save a corn plant from the attack of bacteria. This method is used in almost each and every plant in order to make it resistance against harmful pests and microorganism. By using this technology, the cost of production on the growing of crop decreases which gives more profit to the farmers as well increase the overall productivity of that corn crop.
